[xemacs-hg @ 2003-03-01 07:25:26 by ben] build patch Makefile.in.in: Move src deletions to src/Makefile.in.in. dump-paths.el, dumped-lisp.el: Delete. Combine stuff into setup-paths.el. find-paths.el: Removed. Make this file contain generic routines only. Move stuff to compute Emacs roots to setup-paths.el. startup.el: Removed. Move these variables into setup-paths.el. setup-paths.el, startup.el: Removed. Combine all high-level code for computing the paths into setup-paths.el. Create new function startup-find-load-path to encapsulate all logic for computing `load-path'. Eliminate invocation-directory and invocation-name parameters since there is no point (false generality) -- the code references other globals, which cannot be specified. Eliminate some code duplicated between setup-paths.el and startup.el. Clean up the debug-paths code and output load-path in addition. Add logic to paths-emacs-root-p to support separated source and build trees. loadup.el, make-docfile.el, update-elc-2.el, update-elc.el: Rewrite to allow for separated source and build trees, as may occur in MS Windows. NOTE TO BUILD HACKERS: loadup.el, make-docfile.el, update-elc.el and update-elc-2.el made two assumptions that are no longer correct: (1) The source and build trees are in the same place. (2) They can make assumptions about where `.' is. These files now compute the locations of the source and build roots at the top of the file. *ALL* constant file names or path snippets must now be made absolute using expand-file-name and one of these roots. dumped-lisp.el, packages.el: Removed. Remove some unused lists of Lisp files. packages-hardcoded-lisp (empty, in any case) moved to dumped-lisp.el. startup.el: When a compiled init file is out-of-date wrt the uncompiled version, load the uncompiled version and issue a nasty warning. update-elc-2.el: Force touching of auto-autoloads files when REBUILD_AUTOLOADS was set. update-elc.el: Fix code that checks whether dumping is necessary to check against xemacs.dmp, not xemacs.exe, when Unix and pdump. lwlib-Xm.c: Fix compile warning. README, config.inc.samp, xemacs.mak: -- Major reorganization and cleanup. -- Add support for separated build tree and source tree. -- Delete all support for X Windows building, since it's totally bit-rotten and will never be fixed up. Instruct people to use Cygwin if they want such support. make-build-dir: New script to create a skeleton build tree for use with separated build and source tree compilation. m/acorn.h, m/alliant-2800.h, m/alliant.h, m/altos.h, m/amdahl.h, m/arm.h, m/att3b.h, m/aviion.h, m/clipper.h, m/cnvrgnt.h, m/convex.h, m/cydra5.h, m/delta.h, m/delta88k.h, m/dpx2.h, m/elxsi.h, m/ews4800r.h, m/gould.h, m/hp800.h, m/hp9000s300.h, m/i860.h, m/ibmps2-aix.h, m/ibmrs6000.h, m/ibmrt-aix.h, m/ibmrt.h, m/intel386.h, m/iris4d.h, m/iris5d.h, m/iris6d.h, m/irist.h, m/m68k.h, m/masscomp.h, m/mg1.h, m/mips-nec.h, m/mips-siemens.h, m/mips.h, m/nh3000.h, m/nh4000.h, m/ns32000.h, m/plexus.h, m/powerpc.h, m/sequent-ptx.h, m/sequent.h, m/sgi-challenge.h, m/stride.h, m/tad68k.h, m/targon31.h, m/tekxd88.h, m/template.h, m/tower32.h, m/tower32v3.h, m/ustation.h, m/wicat.h, m/xps100.h, data.c, doc.c, editfns.c, emacs.c, lrecord.h, ntheap.c, process-unix.c, sysdep.c, unexec.c: Delete all support for bit-rotten CANNOT_DUMP. Just use pdump. Makefile.in.in: Lots o' cleanup. Use names like LISP, SRC instead of lispdir, srcdir, for consistency with xemacs.mak and the conventions in the rest of the file. Eliminate use of ${...} in favor of $(...), to make it easier to move code between this file and xemacs.mak. Fix dependency handling wrt NEEDTODUMP to eliminate problems some people (e.g. Vin) have been seeing with non-GNU makes. Write a long section about the subtle but oh-so-important differences in dependency processing between nmake, make, and GNU make. Add unicode-encapsulate target, from xemacs.mak. chartab.c, lrecord.h: Fix crash due to attempt to free objects across dump/undump.

This directory contains C header files containing
operating-system-specific definitions.  Each file describes a
particular operating system.  The emacs configuration script edits
../config.h to include the appropriate one of these files, and then
each emacs source file includes config.h.

template.h is a generic template for system descriptions; it describes
the parameters a system file can specify.

General XEmacs Changes
---------------------------
The following is a list of those changes made globally across all
files.  They are not marked individually in each header file.  All
other changes should be preceded by a comment /* XEmacs change */.


1. Removed all #defines of [read|write|open|close].  This is now
   handled automatically by checking the INTERRUPTIBLE_IO etc. flags.

2. Removed all instances of #undef SIGIO and replaced them with
   #define BROKEN_SIGIO.  Jamie says:

   /* use BROKEN_SIGIO instead of this kludge -- jwz */

3. All instances of HAVE_GETWD, HAVE_DUP2, HAVE_UNISTD_H, NEED_UNISTD_H,
   HAVE_GETTIMEOFDAY and NEED_REALPATH removed.  We detect these
   automatically with configure.

4. All instances of HAVE_X11 replaced with HAVE_X_WINDOWS.  We don't
   support X10 or earlier so the HAVE_X11 define was purged.

5. Most of the signal crap (e.g. redefining sigsetmask, defining
   POSIX_SIGNALS) has been removed.  There are four possible
   signal paradigms that all systems fall into, and we auto-detect
   them in configure and handle them in syssignal.h.

6. Removed references to INTERRUPT_INPUT.  XEmacs does not use
   this bizarre way of reading input.

7. Removed references to BROKEN_FIONREAD.  FIONREAD is used only
   in INTERRUPT_INPUT and in the select() emulator, neither of
   which are supported in XEmacs.

8. Removed references to NOMULTIPLEJOBS.  This is unused in XEmacs
   and in FSF Emacs.

9. Removed references to HAVE_WAIT_HEADER and WAIT_USE_INT.
   They are unnecessary with the cleaned up syswait.h in XEmacs.
   (We autodetect sys/wait.h).  Instead, #define or #undef
   HAVE_UNION_WAIT.

10. Removed BSTRING.  Not used anywhere. (If the header file
    says there are bugs in bcopy() or the like, however, a
    #define BROKEN_BCOPY is added for reference.)

11. Removed #defines of bcopy, bzero, bcmp, index, rindex.
    XEmacs makes consistent use of the ANSI-equivalent
    functions memcpy, memset, memcmp, strchr, strrchr.

12. '#define subprocesses' removed.  Use '#define NO_SUBPROCESSES'
    if they don't exist.

13. References to HAVE_VFORK removed.  configure detects this.

14. Removed references to SYSV_SYSTEM_DIR, NONSYSTEM_DIR_LIBRARY,
    HAVE_SOCKETS, HAVE_SYSVIPC.  configure detects these.

15. Removed defines of HAVE_TERMIOS, HAVE_TERMIO, and
    HAVE_TCATTR (when HAVE_TERMIOS was also defined).
    configure detects these and systty.h automatically defines
    HAVE_TCATTR when HAVE_TERMIOS is defined.

16. Removed SETPGRP_RELEASES_CTTY.  Not necessary any more, with
    fixed definitions of EMACS_SEPARATE_PROCESS_GROUP et al.

17. Removed defines of NLIST_STRUCT.  configure detects this.

18. Removed defines of _setjmp and _longjmp.  configure detects this.

19. Removed all '#define static' business.  Defines NO_REMAP instead.

20. Removed defines of HAVE_MACH_MACH_H.  configure detects this.
